PAX6 and albinism: Several genetic eye disorders falling under infantile nystagmus syndrome (INS) can masquerade as albinism with considerable phenotypic overlap such as dominant PAX6-related oculopathy (OMIM # 136520), SLC38A8-related FVH2 (OMIM #609218), and forms of congenital nystagmus caused by FRMD7 (OMIM #310700) or GPR143 (OMIM #300814) [48,56,57].
